Hi, I recently updated to Android 11 on my Xperia 5 II and received a couple of bugs along with it.

First one is the AOD clock showing the incorrect time, it updates when the screen is double tapped and woken. The other one I've noticed is, I'm receiving some notifications later than I should be doing, I'm guessing android 11 is too strict with hibernating the phone when not active in comparison to Android 10. 

I believe it has also caused benchmark scores to be substantially lower than when tested in Android 10. I haven't personally noticed much of a slow down but I'm not a heavy user but maybe gamers would notice a difference.

I understand bugs are part and parcel of new major firmware updates but I gather Sony delayed the 11 update for the Xperia 5 II because these bugs were flagged up on other Xperia models that received the update 1st, they haven't been fixed so pointless holding the update back if we're in the same boat as Xperia 1 II users.
